DETERMINING A VERIDICALITY METRIC OF A USER PROFILE STORED IN AN ELECTRONIC INFORMATION SYSTEM
Embodiments of the present invention disclose a method, computer program product, and system for determining a veridicality metric of a user profile stored in an electronic information system. The method, computer program product and computer system may include a computing device that inputs an identifier of a user profile and retrieves from an information system at least one element of the user profile based on the identifier. The computing device may submit a search request to at least one further information system. The search request may include a search criterion with at least a part of the element. The computing device may receive at least one search result related to the search request, and determine the veridicality metric based on the at least one element and the at least one search result.
The present invention relates in general to data processing systems, and more particularly to a method and a system for determining a veridicality metric of a user profile stored in an electronic information system.
With the spread of social networks, it has become quite common to connect to new people through these networks without personally knowing someone. This often happens by connecting with friends of friends on social platforms or connecting with someone through a blog, thematic channel, forum, website, etc.
The question then arises if the person behind a social identity can be trusted. Without personally knowing someone, it is difficult, if not impossible, to verify if someone is who they say they are and if any information they provide is real. Trust is usually based on a common network. If a person is a friend of a direct peer in a social network, one is inclined to think that the direct friend knows this person and so the person can be trusted. Unfortunately, quite often, people accept connections from strangers resulting in connections where one has no idea who the other person really is.
For example, online dating facilitates connections between strangers without any physical interaction required. However, many users may be hesitant to participate in online dating services or share information about themselves with others via written communication due to security concerns. Thus, people may be inclined to enter false or misleading information in their online profile. Certifying information provided by participants of online dating services can ease a user's concerns that the information provided by another person is truthful. For Example, there are currently methods of certifying information provided in dating profiles by comparing that metadata of the information provided on the dating profile to metadata on other social networking profiles of the same person. If the metadata matches, a certified status may be assigned to the metadata on the dating profile.
BRIEF SUMMARYEmbodiments of the present invention disclose a method, computer program product, and system for determining a veridicality metric of a user profile stored in an electronic information system. The method, computer program product and computer system may include a computing device that inputs an identifier of a user profile and retrieves from an information system at least one element of the user profile based on the identifier. The computing device may submit a search request to at least one further information system. The search request may include a search criterion with at least a part of the element. The computing device may receive at least one search result related to the search request, and determine the veridicality metric based on the at least one element and the at least one search result.
The present invention together with the above-mentioned and other objects and advantages may best be understood from the following detailed description of the embodiments, but not restricted to the embodiments.
Embodiments of the present invention will now be described in detail with reference to the accompanying Figures.
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention is provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces unless the context clearly dictates otherwise.
The illustrative embodiments described herein provide a method for determining a veridicality metric of a user profile, i.e. a user account, stored in an electronic information system. The illustrative embodiments may be used for the method for (i) inputting an identifier of the user profile; (ii) retrieving from the information system at least one element of the user profile based on the identifier; (iii) submitting a search request to at least one further information system, a search criterion of the search request comprising at least a part of the element; (iv) receiving at least one search result related to the search request; and (v) determining the veridicality metric based on the at least one element and the at least one search result.
As used herein, the electronic information system may be a social media platform and the user profile may be a social media profile or social media account.
According to the inventive method it can be determined how truthful the characteristics listed by a person on a social media platform of are.
Given a set of data available in the user profile, such as, but not limited to, a photo, a first name, a surname, a date of birth/age, a gender, a city of birth, an address, a phone number, a company name, etc., a user profile may be assessed to determine if the user data us real and if the person behind the user profile is not lying.
In order to verify if the data given by a person on a public profile is real, the proposed solution checks and compares available public data associated to the social identity to obtain a reliability score.
Due to the proposed method for determining a veridicality metric of a user profile stored in an electronic information system it is not necessary to access private databases to check data of the user profile. Further there is no need to leverage user credentials to verify social network data. Advantageously, real-world acquaintances are not queried. The identity behind the user profile is not verified using a third party, e.g. a service company, that may provide a public key infrastructure to verify the identity of peers.
If a new connection, such as, but not limited to, a friend, a colleague, an acquaintance, or an unknown connection, etc., on a social network is to be verified, the application analyzes the published information provided on the social network, e.g. Facebook® (FACEBOOK is a registered trademark of Facebook, Inc.), to determine a list of elements, i.e. published information, that can be used for verification. The list of elements might be dependent on the specific social network and be slightly different from platform to platform.
If an expected element is found in the user profile then it is assigned a score. If the element is also verified a further score is assigned. Scores of each item are added to obtain an overall score for the user profile.
After the list of expected elements has been checked, other elements are taken into account such as, but not limited to, the account age (when the account was created), the number of friends/contacts/direct peers, and the activity history (posted content in the timeline, comments/likes to other users' posts). A score for these items a score may also be assigned.
Given a user profile, a set of elements are searched for in the user profile. If no data has been published in the user profile or the application does not find expected elements, the score for each item may be zero, where zero is the lowest score that can be assigned.
On the contrary, if one or more elements are found in the user profile, the application checks each of them. For each element a score is assigned depending on the result of the verification.
A final reliability score will be assigned to the social network user based on the combination of obtained scores. Each element score might be weighted with a predefined coefficient, which may be fixed for each element according to the importance of each element.
Finally, a report is created to show the reliability score result.
In
Details of the different steps of the verification process are described in the following
A photo and name score may be determined by the equation: Photo and name score=‘element present’בphoto veracity’, where ‘item present’ indicates if a photo is available in the social profile; its value is either zero or one, and ‘photo veracity’ indicates the degree to which the photo is evaluated on a decimal scale from 0 to 1.
As depicted in
If a profile photo is available, it is checked at step S204 to determine if the profile photo is a photo of a person or something else, e.g. a drawing, a cartoon, a photo of a landscape, a photo of a group of people, etc. To understand image content, the picture may be classified through visual recognition software such as, but not limited to, IBM® Watson™ (IBM is a registered trademark of International Business Machines, Corp.; WATSON is a trademark of International Business Machines, Corp.), that analyzes images for scenes, objects, faces, text, and other subjects to provide insights into the visual content.
If the photo profile is not a photo of a person, this item is discarded from further verification at step S206 and the element present is scored with a value of one and the photo veracity is assigned a value of 0.1, for example.
If a photo of a person is available, it may be used as a reference for verification.
Referring to step S208, the photo is searched on the web to determine if it is a photo of someone else, such as, but not limited to, a famous person of the past or the present times or a stolen picture, etc.
If the picture depicts a famous person then it is assigned a value at step S210 with a low photo veracity, such as 0.1, and the following step S212 is not performed.
To understand if a photo represents a famous person it may be searched in an online encyclopedia, web news, etc. Moreover, the occurrences of the photo give an idea of the popularity of the person. If many results are found for the photo, with many meaning, for example, more results than a predefined threshold, then the represented person in the profile photo will be determined to be a famous person.
If the picture is found but it does not depict a famous person, it is determined in step S212 if it is another person. If the photo is found in other social profiles/web pages/blogs with a different name/nickname it is classified as false at step S214 and given a photo veracity score of zero.
Similarly, other social networks and web pages are checked for the profile name at step S216.
If no other profile with the same first name and last name or nickname of the user is found, then it is scored in step S218 with a photo veracity of 0.4, for example.
If other profiles with the same name are found in other social platforms, then the photos are compared at step S220. If the same photo is used, a score of one is assigned to element present at step S222 with a photo veracity of 0.6, for example.
If a different photo is found but it can be determined at step S224 with a sufficient degree of accuracy that the photo depicts the same person, a score of one is assigned to the element present, i.e. the profile photo, at step S226 with a high photo veracity of 1.0, for example. Otherwise, at step S228, a score of one is assigned to the element present, i.e. the profile photo, with a photo veracity of 0.3, for example.
To determine if different photos depict the same person techniques of image recognition may be used.
The company score is evaluated by taking into account a top professional network, such as but not limited to, LinkedIn® (LINKEDIN is a registered trademark of LinkedIn, Corp.) and other professional networks. In the following, c1 represents the score for a match with a top professional network and c2 the score for one or more matches with other professional networks.
The final company score is calculated according to (c1+c2)/1.5.
From a social profile it is often possible to see the company where the user of the profile works. For instance, in a Facebook® (FACEBOOK is a registered trademark of Facebook, Inc.) timeline, in the section named “In short”, the company name can be easily retrieved. Therefore, at step S300 a company name is searched. If there is no company name available, a company score of zero is assigned at step S302.
Next the combination of user name and company name is searched at step S304.
If the company name is found in step S300 and combined with the user name in step S304, then it is searched in step S306, if there is a match in professional web pages and social networks. If a professional profile, such as LinkedIn® (LINKEDIN is a registered trademark of LinkedIn, Corp.) profile, is found the highest score of c1 equals to 1 in step S308 is assigned. It can be appreciated that any professional social network may be used.
If the search result in step S306 is negative, but other content is found at step S310, then the company score is assigned an incremental c2 score such as 0.5 at step step S312. If no other content is found, then the company score is set to zero, for example, at step S314. The maximum value for the company score may be 1.
In a social platform, such as, but not limited to, Facebook® (FACEBOOK is a registered trademark of Facebook, Inc.), a user profile may provide personal information including the date of birth. If this piece of information is available at step S400 then it is used for further verification. The provided age may be assigned a value of “x” at step S404. If this information is not present an age score is assigned to zero at step S402.
The language used in posted contents can be analyzed to determine the user age at step S406. To perform this step some solutions are available such as, but not limited to, using Logistic Regression and Support Vector Machines algorithms on text readability features to construct classification models and using open-vocabulary analyses such as differential language analysis to analyze and correlate language features to age.
Data mining techniques may advantageously be used for verifying the age of the owner of the user profile.
The determined user age may be calculated to a value of y.
An error range E, may be established due to the accuracy of the method used to estimate the age. Referring to step S408, it is checked if x equals is found to be equal to y or is within error range of E. If x is found to be equal to y or within the error rage E, the user age is assigned a score of one at step S410. If the user age, x, does not equal y and is not within range E, it may be assigned an age score of zero at step S412.
A maximum value of one may be assigned to the age score.
In this phase, the dates, i.e. timestamps, of the content in a social profile are checked in order to establish the age of the account. For instance, in a Facebook® (FACEBOOK is a registered trademark of Facebook, Inc.) profile, if the posted content, i.e. the timeline, is scrolled, then a menu is displayed, which filters the content by year. Typically, the list is given in a form similar to the following sequence: 2016,2015,2014,2013,2012,2011,1996,1966.
Thus in step S500 the list of years, or timestamps, for posted content on a social media profile may be retrieved. A variable i may be set to n, which equals the number of items in the list of years. Next, it is checked if n equals to zero in step S502. If this is the case the account age score is assigned a value of zero at step S504.
Otherwise, the oldest year can be compared with the birth year in step S506 and then discarded if they match. This may be performed in step S510, where i is decremented by one.
As a standard user posts content every year, isolated years, i.e. years with no posted content, can be discarded as they probably represent a milestone in user's life. For example, Facebook® (FACEBOOK is a registered trademark of Facebook, Inc.) may list significant events in a user's life in a user's timeline, such as, but not limited to, birth year, graduation year, and marriage year, etc., even though the user profile was not active, or even in existence, during the year of the event.
Referring to step S512 it is checked if there are still items in the list, i.e. checking if i is greater than zero. If this is the case, at step S514 consecutive years in the list are checked. If this is not the case i is decremented once more at step S510. Once all items have been checked, the account age is calculated and a score is assigned to this element. Account age is calculated by taking the current year and subtracting the year of item i at step S518 and the account age score is assigned a value of one.
Hence, the oldest year in the consecutive sequence of years is probably the account creation date, so for the listed example above it would be 2011, with the years 1996 and 1966 being listed major life events before the creation of the account and outside the consecutive years of 2011-2016.
If i is not greater than zero at step S512, the account age score is set to a value of zero at step S516.
The older the account, the greater the chances are that the account is associated with a real person. This score could be weighted with the user age. Indeed, if the user is very young then the account cannot be more than a few years old.
This account age score has a value of zero or one, with one being the maximum value that can be assigned.
The reference count may be characterized by a number of documents stored in the information system that refer to the user profile. For example, the number of documents may be the number of posts by other social network users.
If the account under evaluation is mentioned in posts of other social network users, a score may be assigned. The more mentions that are found, the higher the assigned score. This verification step may not be performed if the profile photo or name has been classified as someone famous/known as described above. At step S600, the name is checked to see if it is associated with a famous person. If the name or profile photo is associated with a famous person, the reference score is assigned a value of zero at step S602.
If the name or profile photo is not associated with a famous person, a score is assigned to this item based on the number of found references. Therefore, in step S604 the number of mentions of the account in posts of other social network users, is retrieved. The number of mentions may represented by z.
Referring to step S606, it is checked if z exceeds a value δ, which may be set to given threshold. The reference score is calculated using a mathematical function that takes into account the number of found references above the threshold. Here a simplified way is shown to evaluate the reference score but other functions may be implemented. If the value of z exceeds a value δ the reference score is assigned to one in step S608, otherwise it is assigned to zero in step S610.
Having performed the verification steps an identity score may be generated. This final score may be calculated summing the resulting score from each verification step using the equation: identity score (%)=(s1+s2+s3+s4+s5)/5×100, where s1=photo and name score; s2=company score; s3=user age score; s4=account age score; and s5=reference score.
The final reliability score may also be a combination, instead of a mere sum, of the resulting scores from the verification steps. Indeed, each element score may be weighted with a predefined coefficient, which may be fixed for each item according to the importance of each element for the specific embodiment.
An identity score report 700 is produced to show the final identity score. In
Thus determining the veridicality metric may comprise calculating at least one score value based on the at least one element of the user profile and the at least one search result.
Advantageously determining the veridicality metric may comprise calculating a weighted sum of the multiple score values, if more than one element is searched, wherein at least one score value is based on the at least one element of the user profile and the at least one search result. The score values of the different elements may be weighted with predefined coefficients attributed to one element each.
Input module 302 may be configured for receiving an identifier of the user profile. Retrieving module 304 may be configured for retrieving at least one element of the user profile based on the identifier from the information system. Search module 306 may be configured for submitting a search request to at least one further information system, a search criterion of the search request comprising at least a part of the element. Receiving module 308 may be configured for receiving at least one search result related to the search request. Determining module 310 may be configured for determining the veridicality metric based on the at least one element and the at least one search result.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
